A thousand years ago the area around the confluence of Trout Brook and Phalen Brook near the Mississippi River was a marshy flood plain. By the early 1900s, the entire delta had been expanded by filling and became an industrial railroad corridor. As rail use decreased in the 1970s, the land was largely abandoned and buildings and tracks were removed.
